VAPOR-LAMP.

Specification of Letters Patent No. 28,691, dated June 12, 1860.

To all whom it may concern:

Be it known that I, G. WV. RICHTER, of Madison, in the county of Morgan and State of Georgia, have invented a new and Improved Lamp; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a vertical central section of a lamp constructed according to my invention. Fig. 2, is a detached external view of the wick tube and portion of the cap. Fig. 3, is a detached inverted plan of a tube cap for regulating the size of the flame.

This invention relates to an improvement in that class of lamps which are designed for burning these hydrocarbons that volatilize and gasify at a low temperature, such for instance, as a combination of turpentine and alcohol generally known as burning fluid the light or spirituous coal oils, etc.

The invention is an improvement on a lamp recently patented by me, the Letters Patent hearing date February 22d, 1839, and its object is to more fully carry out the principle involved in the patented lamp alluded to, to wit, the keeping of the font and consequently its contents at a low temperature, thereby preventing explosions and also to prevent the charring or burning of the wick, and the regulating of the volume of flame to increase or diminish the light as may be desired.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the lamp font supported by a proper pedestal B. The lamp may be constructed of any of the known materials now used for such purpose. Within the font A, a cylindrical chamber C, is placed. This chamber extends down a suitable distance withinthe font and its lower end communicates with the external air by two or more lateral tubes 64, a, and the lower end of the chamber communicates by means of a tube D, with the upper part of the pedestal B, which is hollow and perforated at its sides as shown at 6.

Within the cylinder C, a cylinder E of smaller diameter is placed. The cylinder E, need not extend quite down to the bottom of cylinder C, but within a short distance of it, and be secured therein by springs b,

which bear against the cylinder C. The cylinder E, is lined wth a layer of cork F, at its side and bottom the top being open.

G, represents the wick tube which is attached to the bottom of the cylinder C, and concentric with it the bottom of the tube of course being open to allow the wick H, to extend down within the font A. The wick tube is encompassed by the cork lining F, of cylinder E, but a space 0, is allowed between them with the exception of the cork at the bottom of said cylinder. The upper end of cylinder 0, is covered by a cap I, the lower part of which is perforated as shown at aZ. The upper part of the cap extends over the cylinder E, and is filled with cork e, a space f, being allowed around the wick tube corresponding with the space 0, below in cylinder E.

In the lower part of the wick tube G, a cork ring is placed. This ring is intended to serve as an insulator between the lower part of the wick tube below cylinder E, and the chamber C. The upper part of the wick tube is also lined with cork as shown at h, and within the upper part of the wick av perforated pointed tube 2', is placed, the upper end of said tube having a button 1', on it with a piece of cork 75, attached underneath it, the cork 7c, beingof inverted conical form and the upper end of the cork h, being made concave corresponding inversely with the form of the cork h. A space is allowed all around the wick between it and the tube G, with the exception of the upper and lower ends of the tube, and the upper end of said tube is covered by a cap I, which is perforated, as shown at Z.

J, is a cap which is attached to the lamp by a chain m, and rod n. This cap is made of such dimensions that it may when necessary be fitted over the tube cap I, and cover a portion, say one half of the perforations Z, and thereby diminish the number of jets, the cap J, being slotted at its lower end at regular intervals corresponding with every alternate hole Z, in cap I.

From the above description it will be seen that the font A, is well insulated from the wick tube G, and wick H, the latter not being much in contact with the tube and insulated by the corks g, h, at its upper and lower ends. The wick tube is also insulated from the cylinder E, by means of the cork lining F, and space 0, and the cork e, and

space f, in the cap I. The insulation is rendered complete by the draft of air passing up through the cylinder C, in the direction indicated by the arrows. The draft being increased or made greater than in my patented lamp, previously alluded to in consequence of the air being admitted directly into the lower part of cylinder C, through the tubes a, a, and D.

In consequence of having the upper end of the wick H, inclosed between the cork surfaces 71,, 7c, the ends of the wick are prevented from being burned or charred by the heat, the non-conducting property of the cork protecting it. The fluid in the font A, is very slightly warmed, it being when the lamp is burning but a trifle higher than the atmosphere at an ordinary temperature. The wick H, may be ignited by a taper K, placed in the aperture through which the font is sup plied with fluid. The taper will therefore be always ready for use. It is applied to the cap J, in an ignited state in the usual way.

I do not claim broadly the employment or use of a draft chamber encompassing a cylinder which surrounds the wick tube for such device has been previously used, but arranged in a different way from that herein shown and described, but,

I do claim as new and desire to secure by Letters Patent 1. The arrangement of the air pipes a, a, D, and draft tube C, as and for the purpose herein shown and described.

2. I do not claim broadly the insulation of wicks and wick tube by means of cork or other non-conductor, but I do claim the employment of the cork layer F, in combination with the cylinders E, C, and tubes a, a, D, as shown for the purpose specified.

3. I claim the lining of cork h, or other suitable non-conducting substance placed in the upper part of the wick tube G, in connection with the cork or other non-conducting substance is, attached to the under side of the button j, of tube i,]:, and i, being arranged relatively with the top of the wick II, to operate as and for the purpose specified.
